Quantum Suicide is a scientific thought experiment. The scientist sits
in front of a gun that is set up to either trigger or misfire, depending
on the decay of a radioactive atom. With each run of the experiment, there
is a 50% chance the gun will trigger. Under the Copenhagen interpretation
of quantum mechanics, the gun will eventually kill the scientist. But
if the ‘many-worlds’ interpretation is correct, then at each
run of the experiment there will be a universe in which the scientist
lives, and another in which he dies. The scientist can only ever be conscious
of the world in which he LIVES, and so never seems to die. This leads
to the fanciful speculation that the many-worlds interpretation implies
all conscious beings are immortal.
(Imagine the scientist, realizing he cannot die, stepping outside the
lab and seeing for the first time what is worthwhile about existence).

Many years ago, I had a lucid dream in which I was on my back on a little
boat floating slowly along a dark cavern. Lining the walls were stone
angels. Before I passed them, to float on into the darkness, I had time
to ask them questions about my life. They answered without moving their
lips. I heard instead a deep voice at the back of my head. The advice
was 'All you can do is love, the rest is out of your hands.' (The song
is more concerned with things that came to mind a couple of years later
but those angels want to be a permanent part of the background) - Barry
Kavanagh.

When it came to writing songs, I used only chord changes that I found
emotionally affecting, I would find a melody to go with them and then
I would work on the lyrics to match. Each song was supposed to be unified
in this way. Those were my only criteria - Barry.
